Glaciers and ice patches can sometimes hold remains for thousands of years in a deep freeze, preserving delicate materials like feathers, skin or sinew. Even a mummified human body can rest in a limbo. It is an archeologist's dream.

The glacier archaeology program of Innlandet, a Norwegian county, has a giant prehistoric deep freezer. When we find stuff it is usually old. Some of these artifacts are still usable.

Due to climate change, glaciers and ice patches are melting at an unprecedented rate, and these ancient time capsule are about to thaw out for the first time in thousands of years. Archaeologists are trying to keep up with the wealth of information that may soon begin to degrade as it is exposed once more to the elements.

The Iceman Cometh

When tourists found tzi the Iceman on a glacier in 1991, they didn't know how old he was. The mummy is named after the glacier in the tztal Alps.

An unprecedented discovery was the preservation of a naturally mummified man who was close to his death.

Pil claims that tzi is the Holy Grail.

Researchers have drawn a lot of information from the body that was frozen for thousands of years. He probably died from an arrowhead in his back. Scientists think he was in need of a dentist and may have had stomach issues after eating his last meal. According to some research, some of the tattoos on his body could have represented a type of treatment similar to anaphylactic shock.

The complete genome of the Iceman has been mapped.

Ancient Reindeer Hunts

There was an increase in artifacts in Innlandet County when there was a large melt. There were a lot of artifacts coming out of the ice.

Many materials related to ancient reindeer hunts were found in the ice patch.

How these hunts played out was revealed by the way the artifacts were arranged. Archaeologists found arrows and stakes that were used to direct reindeer towards hunters. This kind of discovery can show some of the limitations of glacier archaeology.

Glaciers aren't static blocks of ice. They move like slow rivers and often destroy artifacts in the process. Artifacts covered in ice hundreds of years ago could travel some way before they are pushed out at the end of the glacier.

Most glaciers won't hold artifacts for more than 500 years. When artifacts are found in these areas, they are often moved from where they started. Ice patches don't move as much as other artifacts do. The melting at the surface can cause artifacts to wash down.

Mountain Passes

Pil says that some of the best information comes from glaciers and ice patches. tzi was found in a mountain pass. There are a lot of different kinds of hunting sites in these passes. A 4,400-year-old arrow with a blunt end was discovered by Pil in 2011. If loaded onto a bow, it wouldn't have been small enough to penetrate anything. Researchers determined that it was a toy.

It's possible for researchers to learn a lot from arrows because of the preserved material. They can learn how hunting societies used materials like wood and birds.

Thousands of artifacts were found in the pass. Archaeologists walk close to each other along the edge of the melt, trying to spot artifacts. Archaeologists found a wool tunic and leather shoes from the A.D. 9th century. The remains of a dog were found in the year 2019.

Glacier archaeology grew from a small group of dedicated people. Archaeologists in Norway were not prepared for the big melt in 2006 because there was no program for dealing with it. Inlandet County Council and the Norwegian government funded Secrets of the Ice.

Other amazing discoveries have been made by other researchers. An atlatl, a type of device used to hurl spears, was found in the national park.

Pil says that glacier archaeology has become a global phenomenon.
